About
Data doesn’t drive decisions on its own… but the right analysis can change the direction of an entire organization. I’m a Data Analyst and Data Operations Lead at Mersal Foundation, specializing in transforming messy, unstructured data into scalable systems that support real business decisions. I don’t just analyze data… I solve problems like: Lack of visibility in performance Fragmented data across multiple sources Slow, manual reporting processes By leveraging SQL, Excel, Python, Google Sheets, and Power BI, I build structured databases, automate workflows, and design interactive dashboards that turn complexity into clarity. One of my key achievements was leading the transformation of 100+ fragmented files into a unified, enterprise-ready database—reducing reporting time by 75% and enabling faster, more accurate decision-making. I currently lead a data team, ensuring high-quality data collection and delivering advanced analytical reports to internal leadership and international partners such as UNHCR, supporting strategic planning with reliable, data-driven insights. What sets me apart is my approach: I start with understanding the business and defining the right KPIs before building any dashboard—so every number tells a story, and every insight drives action. I’m passionate about data quality, innovation, and building scalable systems that empower organizations to make smarter decisions. I’m always learning, always improving, and always looking for new challenges where I can create real impact. Let’s connect and explore how data can drive better decisions.!
